RIDING-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 431,980, dated July 8,1890.

Application filed February 13, 1890- Serial No. 340,327. (No model.)

To alZ'whom it may concern.-

Be it known that I, JAMES IIERVA JONES, a citizen of the United'Stat-es,residing at Rockford, in the county of Vinnebago and State of Illinois,have invented certain new and useful Improvements in Cultivators, ofwhich the following is a specification.

This invention relates to a class of cultivators employing parallelswinging drag-bars,

IO and employed in connection with a supporting-frame carrying a driversseat and the nec essary adjusting devices.

The object of this invention is to construct a drag-bar having a rearsection pivoted thereto, said section extending obliquely to thedragbar, thus forming a support for two shovels.

A further object is to construct a drag-bar and rear section withcross-ribs, forming aseries of truss-bars to resist transverse andtorsional strains.

The further object is to secure the inner shovel to the rear section bythe employment of a bracket entering a socket and held in 2 5 place by abolt.

The further object is the application of a single spring acting to liftthe drag-bar and hold the lifting-lever in engagement with the toothedsegment.

The further object of this invention is an adjustable bail for quicklyand easily adj usting the width of the beams in relation to each other.

In the accompanying drawings, Figurel is 3 5 an isometrical representionof such portion of a cultivator as I deem necessary to illustrate myimprovements. Fig. 2 is an isometrical representation of one arm of theadjustable bail. Fig. 3 is an isometrical representation of the rearsection of the drag-bar, showing the socket which receives a bracket forholding the inner shovel-standards in position. Fig. 4 is an isometricalrepresentation of the bracket employed to hold the inner shovelstandardin position. Fig. 5 are side elevations of the forward part of thedrag-bar,

showing the construction of the ribs on each side.

The parts of a complete riding-cultivator 5o (notherein shown) may be ofany of the known varieties, and I deem it necessary to show only suchparts within which my unprovements have a close connection.

I have constructed a lifting device for the purpose of raising the beamsor drag-bars to disengage the shovels from the ground. The beams arepartly lifted by the hand-lever 1 and partly by the bar-spring 2. Thisbarspring 2 is made to serve two purposes byits teusionnamely, that oflifting a consider 6o able part of the beam and also that of holding thehand-lever 1 in engagement with the teeth of the quadrant 3 whenrequired. This object is attained by placing the spring 2 in such aposition that its free end will move in a plane obliquely in relation tothe plane of the movement of the hand-lever 1. With the free end of thebar-spring 2, connected to the hand-lever l by the hook 4 on theopposite side of the fulcrum 5 from the teeth 6 of the quadrant, thespring expends a part of its force in raising the beams through theintervention of the suspension-rod 7 between the lever and the beam. Thespring, also, by virtue of its oblique position, draws outwardly inopposition to the plane of the quadrant, and as a result that part ofthe lever on the opposite side of its fulcrum is drawn inwardly towardthe quadrant. Thus the teeth of the lever and the teeth of the quadrantare held in engagement. The flexibility of the spring allows the leverto be disengaged from the quad rant when it is required.

All straddle-row, riding, and combined cultivators are provided withbails or sway-bars for the purpose of holding the beams and the shovelsa proper distance apart on each side of the row of plants. They arearched to allow tall plants to pass beneath. The shovels are required tobe adjusted to different widths between them, according to the size ofthe plants. This has usually been done in an imperfect and unhandymanner. Iconstruct a bail with what may be properly called aninstantaneous adjustment, by means of which the beams and shovels canbeinstantly set to or from each other. I attain this re sult by makingthe bail in two parts or halves 8, which may be duplicates. The tops 9are segments of a circle. Each part has a nipple 10o 16 upon its surfaceanda slot 11 near its end. The two parts are placed upon each other withthe nipple of one part in the slot of the other and secured with awasher on the end of each nipple and a rivet 12 through it. The twoparts will now slide freely upon each other around an imaginary centerof a circle. The circular motion will expand or contract the lower endsof the bail in relation to each other. When the two beams are attachedto these lower ends in any preferred manner, they will expand orcontract as the bail is adjusted.

To secure the bail and hold the shovels in any required position Iprovide projections or lugs 13 at the crown of each arch on the outsideof each part, which are placed radially with the imaginary center and atequal distances apart. A bifurcated clip or double key 14 is prepared,and when any of the two spaces between the lugs on the bailareeoincident with each other on each side, the key is thrust down witha leg in a space on each side and the bail with the shovels are heldfirmly in position. sition it is only necessary to lift the key 14 andplace it in any other two coincident spaces. It is evident that if thelugs 13 were formed on the inside surfaces of the two parts of the bailinstead of on the outside and a single key instead of a double key 14was inserted in coincident spaces the same result would be attained. Thebail is held in an upright position by attaching the key 14 in a freemanner to one end of a brace=rod 15, while the other end is attached ina free manner to the frame of the cultivator.

My improvements of the beams 'or dragbars 16 relates to that classcalled parallel beams, wherein the rear sections 17, to which theshovels are attached, are hinge-j ointed to the forward sections 16 andthe hinge 18 e011- trolled by a jointed rod 19 parallel with the forwardsection. The object of the parallel beam is to hold the shovels withtheir faces at right angles tothe line of draft at all times when thebeams are swinging from side to side. The ordinary method ofconstructing such beams is with a T-head or cross-head hinged to therear end of the forward section and held in free jointed position by aparallel rod. To attach the shovels to this cross-head, with one shovelleading the other, as required in practice, it is necessary to provideone straight standard and one crooked standard for them.

The purpose of my improvement herewith is to provide a substitute forthis cross-head constructed in a cheap and durable manner, and adaptedto allow a pair of duplicate standards for the shovels to be usedinstead of difierent ones, thus saving a considerable expense andweight. I accomplish this by extending the rear section 17 of the beam16 in a line oblique to the line of draft, from the hinge-joint 18 tothe place where the perpendicular standard 21is attached. This strong Tochange to another po-' and simple form allows the shovelto be placed ata proper working distance sidewise from the longitudinal center of thebeam.

To place the forward shovel a proper workin g distance on the oppositeside of the longitudinal center of the beam, I provide a boxbracket 22of novel form projecting inwardly from the beam. My invention herewithconsists in the peculiar method of attaching this bracket to the rearsection 17. In the side of the beam I make a recess 23 of rectangular orbox form, and the inner end of the bracket 22 is also of box form, thesize of which is the same on the outside as the recess in the beam isinside. The box of the bracket is made to enter the box in the beam in aclosefitting manner. External shoulders 24 are formed on the bracket tolimit its entrance into the beam. A bolt is passed through the beam, thebracket, and the shovel-standard, and all are secured firmly together.This is the strongest possible connection of two parts to resist theleverage of the shovel when working in the ground. It is my purpose tomake the rear section 17 of the beam with the maximum strength and aminimum weight to resist the rearward and transverse leverages of therear shovel. To this end the principal body of the section is formed ofa thin web 26, with its surfaces in a perpendicular plane. This web isre-enforced on its upper and lower edges with wide flanges 27. \Vithinthese flanges and upon the surfaces of the web are oblique ribs 28,which cross each other, forming a truss. Placed thus they are in thebest possible form to resist the rearward strain of the shovel. Thecrossings of the ribs 28 on one side of the web are half-way between thecrossings of the ribs on the other side, lengthwise of the section, asshown at Fig. 5. Thus the center of each rib on one side crosses thecenter of each rib on the other side. This arrangement of ribs producesa very powerful resistance to any torsional or transverse strains of theshovel, and has but little weight.

I construct the body of that part of the beam forward of the hinge-joint18 in precisely the same manner as the rear section and for the samepurpose, namely, with a thin central web 29, re-enforced on its upperand lower edges with flanges 30, and having between them oblique ribs31, forming trusses. The ribs on one side of the Web are placed inrelation to the ribs on the other side in the same novel manner as uponthe extension 17 in rear of the hinge-joint.

It is evident that the truss-ribs above described may be applied to adrag-bar of but a single piece, as heretofore constructed, and in theclaims where I speak of a drag-bar I mean a drag-bar composed of asingle piece or of sections having its entire length or any of itssections provided with the truss-ribs.

I claim as my invention- 1. The combination of a drag-bar, a quad- IIOrant, a bar-spring attached to the quadrant,

its free end moving in a plane oblique to the plane of the quadrant, anda connection between the spring and drag-bar, substantially as setforth.

2. The combinationof a quadrant, a hand lever, a bar-spring attached tothe quadrant, its free end moving in a plane oblique to the plane of thequadrant, and a connection between the spring and hand-lever, wherebythe lever is held in engagement with the quad rant, substantially as setforth.

3. The combination of a drag-bar, a quadrant, a hand-lever, a bar-springattached to the quadrant, its free end moving in a plane oblique to theplane of the quad rant, and a connection between the spring andhandlever and between the spring and drag-bar, substantially as setforth.

4. The combination, with the drag-bars, a bail or sway-bar composed oftwo sections adj ustably connected together, each section provided withlugs, and a key engaging the lugs and holding the bail at the requiredadj ustment, substantially as set forth.

5.
